Remaining consistent, keeping up with traffic, and not being an asshole who blocks lanes is the bigger key.

People want to drive faster? Go ahead. In the end they aren't wasting that much energy and might just be saving some by not having to idle in traffic an extra 5-10 minutes on their daily commute if lucky. Worse for others.

There's some lights on the way to work that are timed to occasionally let you get through if you go 12 above instead of under 10. Almost everyone on their commute hits that 12. You get some regulars who don't, not too big a deal, get in the right lane or more simply, let people have room around you to pass.
